Discussion

Viola odorata occurs in small colonies; individual plants are interconnected by stolons.

The flowers of Viola odorata are noted for their fragrance; some plants are more fragrant than others. It is native to Eurasia and assumed to be introduced in North America where it is usually found in areas associated with human habitation, including parks, lawns, and roadsides. A substantial industry revolved around the commercial production of violets in England, France, and the United States from prior to 1895 and into the 1900s (R. E. Coombs 2003). Viola odorata is sometimes found in remote locations not easily explained by anthropogenic influence, for example, Clearwater Mountains, Idaho. It is available through the nursery trade and is cultivated as a garden plant and occasionally reported as an escape. Viola odorata is grown in southern France for essential oils used in perfumes, flavorings, and toiletries, and also for the production of the sweet, violet-colored liqueur called parfait amour (V. H. Heywood 1978).

Viola bicolor is the only pansy native to North America (V. B. Baird 1942; J. Clausen et al. 1964; A. E. Radford et al. 1968) and is the only annual Viola species that produces cleistogamous flowers (Baird; A. Gershoy 1934). Roots of V. bicolor have the odor of wintergreen when crushed (W. J. Hayden and J. Clough 1990).
